摘要： A geohash based cover for a geometry whose uncertainty is described as a circle with center point and a radius is disclosed. In one example, a geohash cover is computed that does not require any expensive geodesic calculations, providing roughly an order of magnitude improvement in speed up of cover calculation. In another example, distance computations are exact compared to a conventional process. In another example, the geohashes returned by the technique can vary between 4 to 9—with a median 6 (a certain conventional process would always return 9 hashes (all the 8 neighbors and the self geohash)). In another example, results are accurate, while still avoiding expensive geodesic computations.

摘要： An aspect of this invention is a computer-executable method for distributing one or more features associated with information to be transported by a communications network that includes a plurality of end nodes interconnected via a plurality of network nodes. The method includes receiving one or more features associated with information to be transported by the communications network, wherein the one or more features are specified at an end node of the plurality of end nodes for receipt by a network node of the plurality of network nodes; responsive to the one or more received features, configuring at least a portion of the communications network to perform actions on information based upon the features; receiving the information using the plurality of network nodes; and based at least on the received features and the configuring, performing one or more actions with the information. Illustratively, the one or more actions comprise sending the information to one or more edge entity nodes in accordance with the configuring and the received features.
